Question: A tank of area Ao is draining in laminar flow through a pipe of diameter D and length L, as shown in Fig. P4.92. Neglecting

A tank of area Ao is draining in laminar flow through a pipe of diameter D and length L, as shown in Fig. P4.92. Neglecting the exit-jet kinetic energy and assuming the pipe flow is driven by the hydrostatic pressure at its entrance, derive a formula for the tank level h(t) if its initial level is ho.
